KeyTransformer registration is required on all nodes of the cluster, in case of custom keys ------------------------------------------------------------------------------------------- Key: ISPN-2575 URL: https://issues.jboss.org/browse/ISPN-2575 Project: Infinispan Issue Type: Feature Request Components: Querying Affects Versions: 5.2.0.Beta5 Reporter: Anna Manukyan Assignee: Sanne Grinovero Fix For: 5.2.0.CR1 Attachments: ClusteredCacheTest.java The case is the following: I have a clustered cache on which I want to perform a search. I'm doing the following: I'm initializing SearchManager on node1, I'm registering a custom key transformer for my key using the created searchmanager, but then when I'm trying to put data into the cache on node1 (which is in REPL_SYNC mode with cache on node2), I'm getting the exception: java.lang.IllegalArgumentException: Indexing only works with entries keyed on Strings, primitives and classes that have the @Transformable annotation - you passed in a class org.infinispan.query.test.CustomKey3. Alternatively, see org.infinispan.query.SearchManager#registerKeyTransformer When I'm initializing the SearchManager using node2 cache and register the keyTransformer on it as well, then everything works perfectly, even though I am not using the second created SearchManager. The test which reproduces the issue is attached to the jira. Please see the test case: testSearchKeyTransformer()
